THEODORE O. PROUTY, OF AURORA, ILLINOIS, ASSIGNOR TO WILCOX MANUFACTURING COMPANY, OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

WHEEL FOR DOOR-HANGERS. I

I Application filed February 25, 1905.

To all whom it may concern:

Be it known that I, THEODORE O. PROUTY, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in WVheels for Door-Hangers, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to Wheels for door hangers, and it has for its object to provide a new and improved wheel particularly adapted for use in door-hangers, but which may be applied to a variety of other uses. I accomplish this object as illustrated in the draw ings and hereinafter described.

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure 1 is a vertical section, illustrating my improved wheel as applied to one form of door-hanger; Fig. 2 is a sectional view on line 22 of Fig. 1, certain parts being broken away Fig. 3 is a vertical section on line 3*?) of Fig. 4 Fig. 4 is a side elevation of the wheel shown in Fig. 3, part of a door-hanger frame being illustrated and Fig. 5 is a sectional view, illustrating the manner of forming the wheel.

Referring to the construction shown in Figs. 1 and 2,- 56 indicate side-plates, which form the sides of the wheel and are circular in form. As. shown in Fig. 1, they are also concavo-convex and provided with outwardly-bent rim-portions 7-8, respectively. The side-plates 56 are secured to the opposite sides of a central disk 9 which forms the tread of the wheel, the rims 78 projecting beyond the tread, as shown in ig. 1. The side-plates 5-6 and tread 9 are all mounted upon a hub 10 in the form of a sleeve, and the side-plates are held firmly in place on the disk by circumferential flanges 11 '12 formed near the opposite ends of the sleeve 10, said flanges being struck up by means of a suitable die, as disclosed in Fig. 5.

It will be understood that the side-plates are made of sheet steel, or other suitable material, as is also the hub 10,- said hub being best formed from a piece of sheet metal' rolled into cylindrical form. The tread 9 may be made of any suitable material, such as vulcanized fiber.

Specification of Letters Patent.

Patented July 28, 1908.

Serial No. 247,312.

In, order to prevent turning of the sideplates upon the disk 9, as well as to keep the plane of the tread perpendicular to the axis of the hub, projections 14 are formed in each side-plate, which slightly penetrate the disk 9 and lock the parts against such motion one upon the other. Preferably three of the proiections 14 are provided on each side-plate, but a greater or less number may be employed, as desired. Furthermore, as shown inFig. 4, the side-plates are so fitted to the disk 9 that the projections of one side-plate are in staggered relation to those of the other.

In Figs. 1 and 2 I have shown my improved wheel arranged for use in connection with roller bearings 15, running on an axle 16 mounted in a hanger 17. With this construction the hub 10 is tubular in order to receive the rollers 15.

In Figs. 3 and 4 I have shown my improved wheel mounted on a solid axle 18 having its ends provided with taper-bearings 1920 arranged to run in a slot 21 in the side memhers 22-23 of another form of hanger.

That which I claim as my invention and desire to secure by Letters Patent is,

1. A wheel, comprising a hub, concavoconvex side-plates mounted on said hub and coacting to form a wheel, the convex faces of said side-plates being outermost, and flanges formed upon the outer surfaces of the hub between said side-plates and the adjacent end portions of the hub for securing said sideplates upon the hub, said flanges being at a distance from the en'ds of the hub.

2. A wheel, comprising an intermediate disk and side plates at opposite sides thereof,

said side plates being of great-er diameter than the tread portion, forming rims at opposite sides thereof, and having projections which engage said disk to prevent movement of said parts upon one another, the projections of one of said side plates being staggered with relation to those of the other, and means for binding said parts together.
